[Bug report] Double backticks for inline code breaks new remark-slide command
Hi,
Somehow, when double backticks (``) surround inline code (eg to put single ` in it), the --- command is not recognized as new slide instruction anymore.
Anyway, I have found a less elegant html workaround.
I was thinking that it could be possible to fix, but it overtakes my skills by far. I'm not even sure whether it is a xaringan or a remark issue.
Here is a reproducible chunk:
---
title: "Backticks issue"
output: xaringan::moon_reader
---
This will break the next slide(s): `` `5` <- "ananas" ``.
---
It seems to be difficult to use `knitr::inline_expr()` in this case.
---
This will work fine: <code>\`5\` <- "ananas"</code>.
---
Something smart here.
Thank you for reading me! Cheers, Anna
PS: such a great package - again, thanks!

By filing an issue to this repo, I promise that
- [x] I have fully read the issue guide at https://yihui.org/issue/.
- [x] I have provided the necessary information about my issue.
- If I'm asking a question, I have already asked it on Stack Overflow or RStudio Community, waited for at least 24 hours, and included a link to my question there.
- If I'm filing a bug report, I have included a minimal, self-contained, and reproducible example, and have also included
xfun::session_info('xaringan'). I have upgraded all my packages to their latest versions (e.g., R, RStudio, and R packages), and also tried the development version:remotes::install_github('yihui/xaringan'). - If I have posted the same issue elsewhere, I have also mentioned it in this issue.
- [x] I have learned the Github Markdown syntax, and formatted my issue correctly.
I understand that my issue may be closed if I don't fulfill my promises.
I had nearly this exact same issue. It was driving me nuts. Thanks for the simple workaround. Hadn't thought of that.
FWIW I think this is an issue with remark.js parser and double backticks. The Markdown code is correctly written asis by xaringan in the HTML to be processed by remark.js
I don't know if double backticks syntax is currently supported by remark. But they surely seem to break the --- slide delimiter.
Maybe we should open an issue there ? 🤔 Did you already ?
Hi @cderv , Thanks for your interest. I didn't, as I have no clue about how to rephrase my initial issue. I don't know enough js to be sure that I'll be understood and to produce a reprex... I would be grateful if you would take the time to do so. However, as we've got the workaround, I don't think that it is an emergency ;-)
Thanks again anyway!
As a workaround you can build (sadly there is no direct download) a static version of remark.min.js and set it within your Rmd:
xaringan::moon_reader:
chakra: "path/to/remark.min.js"
To build remark.min.js from a commit in January 2021 (randomly selected), you can do the following
git clone https://github.com/gnab/remark.git
cd remark
git reset --hard c69c25fa94c45ac8bfa668bee1d878e86517f93a
git submodule update --init --recursive
npm install
node make
Then copy out/remark.min.js to the desired location. This requires a working node installation on your machine.
